Update
Isolated weak convection has dissipated over inland areas early
this evening and skies are mostly clear to partly cloudy.

Anticipate little change overnight with perhaps a slight increase
in mid to high clouds over the SRN zones toward early morning.

Could be some stray showers push nwd into our marine zones late
tonight based on latest radar trends and guidance. Can't rule out
a stray shower affecting the immediate coast after midnight but
only 5-10 percent chance. Dry air in the mid and upper levels
will help allow lows to reach the lower to mid 70s late tonight.

For wed, above well above normal temps again and have tweaked
highs slightly higher given warm sly flow to start the day.

Delayed most precip until after about 1-2pm. An increase in
moisture should bring a little higher coverage of showers and a
few storms as the sea breezes merge over the interior and the
steering flow becomes south-southwest. Rain chances are placed at
about 20-40 percent, with highest chances over interior northeast
fl.

Aviation
Vfr conditions prevail through wed. A low chance of shallow fog
down to MVFR possible ifr at gnv and vqq from 06z to 12z. Chance
of showers and storms for Wed in the aftn but low enough to keep
just vicinity wording in the fcst at this time.

Marine
East to southeast winds near 5-10 kt this evening and become south
overnight. Seas roughly in the 2-4 ft range, slightly higher offshore
beyond about 40-50 nm. Seas dominated by 8-9 second east swells.

Only slight changes for initial conditions for the cwf update.

Rip currents: moderate risk through Wednesday due to onshore
winds and 8-9 second swells.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
